I tried the indenter script. Made the code look worse. "guix lint"
complained about the line length. Furthermore, "guix lint" complains
about the line length when I autoindent. New patch leaves scripted
indent alone.

"guix lint" says pkg-config should be a native-input, but when it is
defined as a native-input it says it fails to make derivatives for
other systems. Since I am not currently able to reconfigure my system,
I'll let someone else handle this problem.

Not certain what you mean. The comment contained two complete sentences.
Comment removed.

I had trouble tredging the documentation to find out how to do this.
Some help here would be appreciated. Until we can fix it as you
suggest, the original code will be sufficient. Added TODO comment
describing the change you suggested.

Given that these descriptions are from the gnurobots authors, I don't
understand why this small change is necessary, but I'll fix.

Recommended fixes made where possible, though I need a bit of help with
other fixes noted above. New patch generated and attached.
